Spectrum Master Programming Manual : EV‑DO Commands : :READ Subsystem
 
:READ Subsystem
This set of commands combines the ABORt, INITiate and FETCh commands. It aborts any current triggering sequence and sets the trigger state to idle. It then initiates a new active measurement (i.e. begins the collection of new data). When the measurement is complete, it returns the result. These commands will not switch to another measurement.
To get the current measurement data, use the FETCh command.
:READ:OTA:MPATh?
Title
Read OTA Multipath
Description
Triggers a new measurement and returns six Ec/Io values, six Tau values, Channel Power, and Multipath Power. It is a combination of the commands :ABORt; :INITiate; :FETCh:OTA:MPATh? In order for the data to be accurate, the Multipath measurement must be the active measurement (specified by :CONFigure:OTA MPATh). The current measurement can be queried using :CONFigure?
Data is returned as 14 comma‑delimited values: six Ec/Io Values in dB, six Tau values in ps, Channel Power in the current user set unit (dBm/W/mW), and Multipath Power in dB. All invalid values are replaced with “‑‑”.

:READ:PFail?
Title
Read PASS/FAIL
Description
Triggers a new PASS/FAIL measurement and returns the results. It is a combination of the commands :ABORT, :INITiate, and FETCh:PFail? The PASS/FAIL measurement must be active. The current measurement can be queried using :CONFigure?

:READ:RF:ACPR?
Title
Read Adjacent Channel Power Ratio
Description
Triggers a new measurement, and returns the power levels for each of the adjacent and main channels (9 total). It is a combination of the commands :ABORt; :INITiate; :FETCh:RF:ACPR? In order for the data to be accurate, the ACPR measurement must be the active measurement (specified by :CONFigure:RF ACPR). The current measurement can be queried using :CONFigure?
Data is returned as 9 comma‑delimited values: The Absolute Adjacent Channel 1 Power, Absolute Adjacent Channel 2 Power, Absolute Main Channel 1 Power, Absolute Main Channel 2 Power, Absolute Main Channel 3 Power, Absolute Main Channel 4 Power, Absolute Main Channel 5 Power, Absolute Adjacent Channel 3 Power, Absolute Adjacent Channel 4 Power. All values are returned in dBm. Note that the values for all five main channel carriers are shown even if the number of carriers set on the instrument is below five.

:READ:RF:EMISsion?
Title
Read RF Spurious Emission
Description
Triggers a new measurement and returns the Marker Amplitude, Marker Frequency, RBW, a Pass/Fail assessment, and the Mask Boundary Frequency for all markers/boundaries. It is a combination of the following commands :ABORt; :INITiate; :FETCh:RF:EMISsion? In order for the data to be valid, the Spurious Emission measurement must be the active measurement (specified by :CONFigure:RF EMISsion). The current measurement can be queried using :CONFigure?
Data is returned as 5 comma‑delimited values for each marker/boundary (40 values total): Marker Amplitude in dB, Marker Frequency in Hz, RBW in Hz, Pass/Fail, and Mask Boundary Frequency in Hz. Markers that are not on will return “‑‑” for Marker Amplitude, Marker Frequency, RBW, and Pass/Fail. All Mask Boundary Frequencies will show normally.

Title
Read RF Spectrum
Description
Triggers a new measurement and returns the Channel Power (Current User Set Unit), Occupied Bandwidth, Channel Power (Watts) and Peak to Average Power measurement results. It is a combination of the following commands :ABORt; :INITiate; :FETCh:RF:SPECtrum? In order for the data to be accurate, the Channel Spectrum measurement must be the active measurement (specified by :CONFigure:RF SPECtrum). The current measurement can be queried using :CONFigure?
Data is returned as 4 comma‑delimited values: Channel Power in the current user set unit (dBm/W/mW), Occupied bandwidth in Hz, Channel Power in fW, and Peak to Average Power in dB.

Read RF Summary
Description
Triggers a new RF Summary measurement and returns the results.It is combination of the commands :ABORT, :INITiate, and FETCh:RF:SUMMary? The current measurement can be queried using :CONFigure?
Data is returned as 9 comma‑delimited values: Channel Power, Pilot & MAC Power, Frequency Error, Spurious Emission, Occupied Bandwidth, Idle Activity, Active Activity, ON/OFF Ratio, Peak to Avg Power. All invalid values are replaced with “‑‑”. Power units are in watt or dBm as per what is set by the user. Frequency is always in Hz.
